The body 110 is composed of a ball-supporting cup 120, a shank 130 and a dentated trench 150. The ball-supporting cup 120 is concavely recessed and disposed at the upper end of the body 110 for supporting a golf ball. The shank 130 extends downward from the bottom of the ball-supporting cup 120 toward the lower end of the body 110 and gradually forms a tapered end for easily penetrating the body 110 of the golf tee 100 into the ground. The dentated trench 150 is disposed on the outer surface of the shank 130, and is composed of a longitudinal groove 152 and a plurality of rectangular slots 154. The longitudinal groove 152 is oriented to be parallel to the vertical direction of the shank 130, and the plurality of rectangular slots 154 are disposed vertically along at least one sides of the longitudinal groove 152.

According to various embodiments of this invention, the body 110 may be made from plastics, metals, synthetic materials (e.g., a synthetic rubber), or natural materials (e.g., wood or bamboo). The body 110 of the golf tee 100 of this invention may be made from any suitable material via any known or equivalent method. For example, the body 110 of the golf tee 100 may be inject-molded from plastics or rubber. Alternatively, the body 110 may be pressed-molded or cut-molded from any metals or natural materials. In optional embodiments, the ball-supporting cup 120 and the shank 130 may be respectively made from different materials. For instance, the ball-supporting cup 120 may be made from the synthetic rubber for prolonging its tolerance to strikes and/or life span; whereas the shank 130 may be made from plastics.

The retaining member 140 may move along the longitudinal groove 152 of the dentated trench 150 and engage itself with the dentated trench 150 on various positions or heights along the shank 130 by locking itself on any of the plurality rectangular slots 154, thereby allows a user to select and adjust the golf tee 100 to a desirable height before subjecting it for penetrating into the ground. The retaining member 140 may be made from plastics, metals, synthetic materials (e.g., a synthetic rubber) or natural materials (e.g., wood or bamboo). However, the body 110 and the retaining member 140 can be made from the same or different materials. In one embodiment, the body 110 and the retaining member 140 are both made from plastics. In another embodiment, the body 110 is made from plastics and the retaining member 140 is made from rubber.

FIGS. 2A-2C are schematic drawings of the body 110 in accordance with various embodiments of this invention.

As depicted in FIG. 2A, the dentated trench 150 of the body 110 is composed by a longitudinal groove 152 and a plurality of rectangular slots 154, in which the longitudinal groove 152 is generally oriented to be parallel to the vertical direction of the shank 130; and the plurality of rectangular slots 154 are disposed vertically along one side of the longitudinal groove 152. As illustrated in FIG. 2A, any two adjacent rectangular slots 154 on the same side are spaced apart by a distance P; and the distance P between any two adjacent rectangular slots 154 is the same in this example; however, the distance P may be different in other examples. For example, the distance P between any two adjacent rectangular slots 154 close to the tapered end of the body 110 may be larger than that at the other end opposites the tapered end of the body 110. Alternatively, the distance P between any two adjacent rectangular slots 154 close to the tapered end of the body 110 may be smaller than that at the other end opposites the tapered end of the body 110. Still alternatively, the distance P between any two adjacent rectangular slots 154 may vary in accordance with other rules or may be changed in an irregular manner.

In another example, as depicted in FIG. 2B, the plurality of rectangular slots 154 are disposed on both sides of the longitudinal groove 152 and parallel to each other along the vertical direction of the body 110, wherein the distance P between any two adjacent rectangular slots 154 on the left side of the rectangular slots 154L is larger than that on the right side of the rectangular slots 154R, thereby allows the user to lock or fix the retaining member 140 at a preferable position by moving and engaging the retaining member 140 to a desirable rectangular slot in accordance with the manner described above in FIGS. 1 and 2A.

Alternatively, as depicted in FIG. 2C, the plurality of rectangular slots 154 are alternatively disposed on both sides of the longitudinal groove 152 along the vertical direction of the body 110; in which the distance P between any two adjacent rectangular slots on the left (i.e., the left rectangular slots 154L) and on the right (i.e., the right rectangular slots 154R) are the same, thereby allows the user to adjust the height of the golf tee 100 in a more accurate or precise manner.

Referring again to FIGS. 2A to 2C, according to one embodiment, the distance P between any two adjacent rectangular slots 154 on the same side is between about 0.1 to about 2 cm, such as about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, or 2.0 cm. Preferably, the distance P is between about 0.2 to 0.5 cm, such as about 0.2, 0.3, 0.4, or 0.5 cm. Any person having ordinary skill in the art may make appropriate and/or numerous alterations to the distance P depending on the market demands and/or product applications.

FIG. 3A is a schematic drawing of the retaining member 140 in accordance with one embodiment of this invention. The retaining member 140 includes an interior cavity 144 and a tab 142 that is extended from the inner surface of the interior cavity 144.
